question 148

Multiple Choice

Which statement about a voltaic cell is not correct?

• A)The standard reduction potential is a measure of the propensity for a reduction half-reaction to occur when concentrations are 1 M, the pressure is 1 atm, and the temperature is 298 K.
• B)A reduction half-reaction with a standard reduction potential, , when reversed becomes an oxidation half-reaction with  .
• C)The standard cell potential, , is a measure of the electromotive force (emf) generated by the cell reactions at 298 K when concentrations are 1 M and the pressure is 1 atm.
• D)The emf of a cell is a measure of the force with which the cell pumps electrons from the cathode to the anode.
• E)The cell voltage measured with a voltmeter is not necessarily the standard cell potential.
